15 Claims.
This invention relates particularly to door han
dies for conveyances such as automobiles and air
handle is swung outward, as in Fig. 2, it may then
be rotated as in Fig. 3 to turn the spindle and re
Special objects of the invention are to provide a
handle construction for releasing the door-secur
tract the bolt.
The invention is applicable to existing forms
of locks and such a lock is here shown, involving
a frame l5, Figs. 4 and 6, attached to the door
planes.
ing bolt and for opening the door, which, when
not in actual use, will ?t smoothly and in effect
he streamlined to the face of the door, which can
be readily brought to position for gripping by the
10 hand and which can be easily operated both to
exert the necessary bolt-releasing force and to
swing the door open.
Further objects of the invention are to provide
a door handle construction having the charac
15 teristics mentioned and which will be adaptable
to, and readily combined with, the forms of door
bolts now in use, which will be of simple, sturdy,
inexpensive construction and which will be prac
tical and e?lcient for the purposes intended.
20
The foregoing and other desirable objects are
attained by the novel features of construction,
combinations and relations of parts hereinafter
described, illustrated in the accompanying draw
ings and broadly covered in the claims.
25
The drawings show a practical and at present
preferred embodiment of the invention, but it
will be understood that the structure may be mod
i?ed and changed in various ways, all within the
true intent and broad scope of the invention.

Fig. 1 is a broken face view of a form of the in
vention applied to an automobile door;
Fig. 2 is a broken top plan view of the door, il
lustrating the feature of pushing in the short
end of the lever handle to swing the longer grip
35 ping portion out within the grasp of the hand;
Fig. 3 is a broken face view similar to Fig. 1,
but showing the handle swung out as in Fig. 2
and rotated downwardly to retract the latch bolt;
Fig. 4 is a broken, detailed view with portions
40 in section partly on the line 4-4 of Fig. 1;
Fig. 5 is a broken detail of the locking elements,
partly in section, as on line 5-5 of Fig. 4;
Fig. 6 is a broken edge view of the door with
the lock incorporated;
45
(Cl. 70-208)
Fig. 7 is a partly sectional exploded view of
parts forming the handle and spindle mechanism.
, As shown particularly in Figs. 1, 2 and 3, the
handle comprises a special operating lever l0
which normally seats ?ush or flat against the face
of the door II and is pivoted near one end at I2
I to provide a short push lever portion 13 by which
the longer handle portion M. Fig. 2, may be swung
out into the full grasp of the hand. This double
ended lever handleis connected with the bolt
55 retracting spindle of the look so that after the
and in which there is mounted a spring-pressed
bolt l6 retractable by a rotary shank or spin
dle H.
In applying the invention to this particular
look, a cylindrical head or enlargement I8 is
formed with or secured to the outer end of the
spindle, and this, in the present illustration, is
made with a cross slot iii to receive the end of
the handle. This spindle head or enlargement 15
provides ample material for the handle-receiv
ing cross slot and for carrying the hinge pin l2.
In the construction illustrated, the slotted end
of the bolt-retracting spindle and the handle por
tion seated in the cross slot are flush, or substan
20
tially flush, with the outer face of the door, when
the handle is not in use, and the gripping portion
H of the handle then seats in a recess 20 so as to
lie substantially flush with the face of the door.
The cross-slotted spindle head is shown as ro
25
tatably supported in a cylindrical bearing 2|,
having a face plate portion 22 (Figs. 5 and 6)
by which it is mounted in the door. The spindle
head is shown as rotatably secured in this bear
ing by a transverse pin 23 operating in an arcuate 30
slot 24, which maybe proportioned to limit the
turning movement of the handle to a de?nite an
gular extent.
In the particular form of the invention here
shown the back of the push portion of the lever 35
handle is hollowed out to provide a recess 25 and
the cross slot of the spindle is angled back to
form a co-extensive recess at 26, these cooperat
ing to receive the spring 21 coiled about the hinge
pin 12 and having one end 28 thrusting against 40
the back of the spindle recess and the other end
29 exerting outward thrust against the push end
of the handle lever. Actually, in the illustration,
the outward thrusting end of this spring is ex
tended through the end of a slide rod 30 which
bears against the back of the lever, as in Fig. 4.
For locking the handle in its seated relation,
the slide rod 30 is shown as operating through a
bearing 3| in the spindle head and as extend
ing back along the spindle to a position in front
of a blocking member 32 (Figs. 4 and 5) which
can be lowered by lever 33 into position to pre
vent backward movement of such rod. The lock
ing lever 33 is indicated as operable through a

2
cam connection 34 from av rotary handle member
35 (Figs. 1, 4 and 5).

of the grip portion of the handle serves to limit
the inward folding movement of the handle, as in
.Fig. 4. While the cross pin 23 positively secures

10 locking slide 31 is further shown as adapted to head It may be formed as an integral part of the
extend into a locking recess 4| in the underside squared shank or spindle H, but it will be ap
preciated that it may be connected with this

A further lock for preventing outward swing
, to lock the handle in its retracted position and to
15 lock the spindle against a turning movement
which would retract the bolt.
.
The cylinder lock 40 is shown as mounted in
the lock‘ housing or casing back of the handle
portion of the lever, Fig. 4, and the covering por
tion of the handle is shown as having a rotary
escutcheon 42 for admitting the key to the lock.
With the operating lever moimted as shown in
Fig. 4, the push end of the lever swings on an
arc intercepting the inner circumference of‘ the
bearing 2|. To accommodate this end of the
lever the bearing is therefore hollowed out
through an arc su?lcient for the full movement
‘
_ of the lever, substantially as represented at 43.
The usual bolt-projecting spring of the latch >
bolt shown has the effect of rotating the spindle I
to bring the handle back into line with its re-'
‘cess in the door and the spring 21 has the eil'ect
of rocking the handle to carry it back and hold
it seated in such recess. Hence the combination
of such spring means has the effect of both turn
ing the handle back into line and retracting it
into its seat so that when released the handle
will automatically ?nd its seat and stay there
until projected through the definite operation of
the push lever.

manner.
The spring 21 through its connection
with. the locking pin 30 (Figs. 4 and '7) serves to 15
hold that pin outward against the inner face of
the thumb portion of the lever so that in the
closed position (Fig. 4) thelslide rod or pin is
ready to have the blocking member 32 slipped
down in back of the same. This blocking mem-' 20
her 32 may brace and guide itself against the '
inner face of the lock casing at 52 in Fig. 4.
The present handle construction is so designed
that it may be readily applied to existing auto
mobile door locks, practically by constructing 25
the handle head I8 to ?t over the'end of the lock
‘shank II, or by making this handle head with
a shank extension equivalent to the part |‘| adapt
ed to replace the shank in the standard look.
This new handle vconstruction also can‘ be ap 30
plied without interfering with the sliding glass
53 usually present in such doors.
'
.The invention may thus be made up practically
as a replacement for present door handles and
at little, if any, additional cost since all' that is 35
required, in the main, is a suitable ‘mounting
which enables the handle ?rst to swing out of its
seated relation in the‘door and then to rotate to
turn the shank in a bolt-retracting direction.
As this ?rst movement is merely to-swing the 40
handle out into a position for grasping by the hand,

shown is at present considered the preferred form, - no great force is required and in the outwardly
